All Universal RAI (URAI) series blowers are heavy-duty positive displacement blowers with a compact, rugged design engineered for continuous duty and maximum reliability. These blowers feature a time-proven lubrication system. The unique “number-8” gearbox design improves oil distribution to the timing gears in addition to extending bearing life.
This series features gray iron housing, carburized and ground alloy steel timing gears secured to steel shafts with taper fit and locknut, and gray iron impellers. Extra-large anti-friction bearings using heavy-duty cylindrical roller bearings on drive shaft to resist V-belt pull. Viton™ brand seals maintain proper lubrication in the bearings.
The standard URAI blower features convenient grease lubrication at the drive end. Bottom brackets allow for great field adaptability meeting the requirements for either vertical or horizontal installation and for any of the four drive shaft positions: top, bottom, right or left. All frame sizes are centered to allow rotation in any direction.
This URAI blower features Dual Splash Lubrication (DSL). There is oil splash lubrication on the gear end and shaft end. The shaft end has two bearings mounted on the shaft and the gear end features a unique “number eight” design in the gear case that when working together improve oil distribution and maximize gear and bearing life. The oil reservoirs have sight glasses to accurately confirm oil level.
The standard URAI line was refined using computer-aided design techniques to incorporate Roots’ exclusive WHISPAIR jet. The WHISPAIR jet uses noise suppression and pulsation reduction techniques. This exclusive WHISPAIR feature can reduce noise by 3-5 dB in typical installations. Like the standard URAI Blower, the URAI-J features a universal detachable steel mounting to allow easy field adaptation to any of four positions and grease lubrication at the shaft end.
This URAI blower combines WHISPAIR design with dual splash lubrication to provide the longest life and quietest performance of the URAI series.
URAI gas blowers have mechanical seals and Viton™ O-rings. The seal system was designed to meet or exceed gas industry safety standards, including provisions for purging gas at the head plates. The URAI gas blower utilizes a removable steel mounting with appropriate brackets for adaptability of the drive shaft position to meet requirements in vertical or horizontal installations.
